A vehicle with an emergency reporting function transmits an emergency report in a case where the vehicle is involved in an emergency. The vehicle includes a vehicle communicator and a vehicle memory. The vehicle communicator transmits the emergency report to an operator terminal. The operator terminal acquires emergency-related information by accessing a memory holding the emergency-related information. The emergency-related information includes limited-access information about the vehicle, an occupant of the vehicle, or both. The vehicle memory holds authentication information to be used to access the limited-access information held in the memory. The vehicle communicator transmits the authentication information to the operator terminal, and causes the operator terminal to acquire the limited-access information from the memory, as a part of the emergency-related information, by using the authentication information received from the vehicle.

A shot detection system for a projectile weapon comprising: an accelerometer, a power source, a memory; and a processor configured to: receive accelerometer data from the accelerometer; for a first region of interest, test a first property of the accelerometer data; and store a shot determination result in the memory.

A vehicle with an emergency reporting function includes a processor, a vehicle communication device, a first calling device, and a vehicle outside occupant detector. The processor determines, by means of the vehicle outside occupant detector, whether an occupant who has been present inside the vehicle before an emergency is present inside the vehicle or outside the vehicle after the emergency. If the occupant is present inside the vehicle after the emergency, the processor uses the first calling device to enable a communication between an occupant inside the vehicle and an operator terminal. If the occupant is present outside the vehicle after the emergency, the processor additionally uses a second calling device to enable a communication between an occupant present outside or inside the vehicle and the operator terminal. The second calling device allows for a communication outside the vehicle.

Systems and methods for authentication using radio frequency tags are disclosed. In one embodiment, a method for approving a requested operation from a secondary user of a resource that is controlled by a primary user may include (1) a back end comprising at least one computer processor receiving, from a mobile application that is executed by a mobile device associated with a secondary user, a requested operation involving a resource that is controlled by a primary user; (2) the back end receiving a unique identifier from the secondary user mobile application, the unique identifier being read by the mobile application from a tag associated with the secondary user; (3) the back end determining that the received unique identifier matches a stored unique identifier that is associated with the secondary user; and (4) the back end approving the requested operation and communicating the approval to the secondary user mobile application.

The present invention concerns systems, a kit and methods for monitoring coupling of a vehicle and a trailer or a trailer and another trailer. The system includes two sensors associated with a turntable of a towing vehicle, said sensors consisting of: a contact sensor configured to detect when a skid plate of a vehicle to be towed is in contact with the turntable; and a locking sensor configured to detect when the locking mechanism is in a locked configuration. The system further including a controller operatively connected to the two sensors and configured to receive output signals from the contact sensor and the locking sensor and to determine whether safe coupling has been achieved based on the output signals.
